Built by Ryan McNaught, Australia’s only Lego certified professional, who built the Colosseum for the Nicholson Museum. Standing more than one metre high, 1.3 metres wide and 1.8 metres long, the Colosseum is ”the most technically challenging thing I’ve ever built,” McNaught says, adding that his fingers often cramp up at night during big builds but, in this case, it was his brain that was left hurting. ”I’ve really got a new appreciation for the Romans and how they made things. For me, the challenge of making something oval-shaped out of square bricks was mind-boggling.”
